Abstract

Moderately well-sorted silica sands of aeolian origin occur at various locations along the South Kanara coast. They contain a very low percentage of heavy minerals. The silica content is comparatively more in the medium-size fraction than in the finer fraction. Higher concentrations of AI, Fe, and Ti are associated with finer fractions. The average silica content (96.6%) shows that these white sands are of high grade quality. The very low magnetic susceptibility values are indicative of low Fe content.
